With his bushy black beard and skullcap, Azhar Usman strides on to the stage with a raucous "Assalam Aleikum."

"For those who don't know what that means, I'll explain it to you," he declares. "It means: 'I'm gonna kill you.'"

This is a piece from Tissa Hami:

One of her jokes deals with the fact that in mosques, women always pray in the back, behind the men. Americans see this as a sign of the oppression of Muslim women, Hami says, but really, "We just like the view." She pauses. "We're praying for a piece of that."

Malaysia's National Space Agency is trying to determine how its astronaut candidates will practice Islam in space. Three of its four astronaut candidates are Muslim, and two will be selected for a future Russian space flight.

Once in their orbiting spacecraft, they will circle the Earth once every 90 minutes. Traditionally, Muslims pray five times per day, at times connected to the position of the Sun in the sky. This will make prayer observance a challenge if they accept a "day" as being just 90 minutes long.

Muslims who travel to space must tackle religious challenges such as performing prayers at zero gravity and ensuring their meals fulfill Islamic dietary conditions, said Saiyad Nizamuddin Ahmad, a United Arab Emirates-based university professor in Islamic studies.

"We are all very hopeful that the efforts by the Malaysian government will inspire other Muslim countries to inaugurate space initiatives," Ahmad said on the sidelines of a conference in Kuala Lumpur to discuss Islamic perspectives on space expeditions.
